Description

Gets a list of files in the current project that match a specified search pattern. The default command gets a list of all files in the project.

The get_files command returns a machine readable list of files in the project, in a design, or in a sub-design such as an IP core or block design. You can filter the results returned by get_files using one of the command arguments such as -of_objects, -compile_order, -used_in, and -filter.

The -compile_order and -used_in options must be used together to return a list of files from the sources or constraints filesets used in synthesis, simulation, or implementation, sorted according to the order of evaluation by the Vivado tools. The -compile_order and -used_in options use complex file ordering rules that can change based on header files, include files, or other language options. You can also filter files returned by get_files according to the USED_IN property, using the -filter option instead of the -used_in option.

You can use the report_compile_order command to generate a report of all files in the sources or constraints filesets, used in synthesis, simulation, AND implementation, sorted into different sections.

Note: To improve memory and performance, the get_* commands return a container list of a single type of objects (e.g. cells, nets, pins, or ports). You can add new objects to the list (using lappend for instance), but you can only add the same type of object that is currently in the list. Adding a different type of object, or string, to the list is not permitted and will result in a Tcl error.

Arguments

-regexp - (Optional) Specifies that the search <patterns> are written as regular expressions. Both search <patterns> and -filter expressions must be written as regular expressions when this argument is used. Xilinx regular expression Tcl commands are always anchored to the start of the search string. You can add ".*" to the beginning or end of a search string to widen the search to include a substring. See http://perldoc.perl.org/perlre.html for help with regular expression syntax.

Note: The Tcl built-in command regexp is not anchored, and works as a standard Tcl command. For more information refer to http://www.tcl.tk/man/tcl8.5/TclCmd/regexp.htm.

-nocase - (Optional) Perform case-insensitive matching when a pattern has been specified. This argument applies to the use of -regexp only.

-filter <args> - (Optional) Filter the results list with the specified expression. The -filter argument filters the list of objects returned by get_files based on property values on the files. You can find the properties on an object with the report_property or list_property commands. Any property/value pair can be used as a filter. In the case of the "file" object, "FILE_TYPE", and "IS_ENABLED" are some of the properties that can be used to filter results.

The filter search pattern should be quoted to avoid having to escape special characters that may be found in net, pin, or cell names, or other properties. String matching is case-sensitive and is always anchored to the start and to the end of the search string. The wildcard “*” character can be used at the beginning or at the end of a search string to widen the search to include a substring of the property value.

Note: The filter returns an object if a specified property exists on the object, and the specified pattern matches the property value on the object. In the case of the "*" wildcard character, this will match a property with a defined value of "".

For string comparison, the specific operators that can be used in filter expressions are "equal" (==), "not-equal" (!=), "match" (=~), and "not-match" (!~). Numeric comparison operators <, >, <=, and >= can also be used. Multiple filter expressions can be joined by AND and OR (&& and ||). The following gets input pins that do NOT contain the “RESET” substring within their name:

get_pins * -filter {DIRECTION == IN && NAME !~ "*RESET*"}

Boolean (bool) type properties can be directly evaluated in filter expressions as true or not true:

-filter {IS_PRIMITIVE && !IS_LOC_FIXED}

-of_objects <args> - (Optional) Get the files that are associated with the specified file, fileset, IP, or reconfig_module objects. The default is to search all filesets. When -compile_order and -used_in are specified, the -of_objects switch will only accept a single fileset, or a single sub-design such as an IP core, Block Design, or DSP design. A sub-design is also known as a composite file.

Note: The -of_objects option requires objects to be specified using the get_* commands, such as get_cells or get_pins, rather than specifying objects by name. In addition, -of_objects cannot be used with a search <pattern>.

-compile_order [ sources | constraints ] - (Optional) Returns the source design files, or the constraint files sorted according to the order of compilation by the Vivado Design Suite.

Note: This option must be used with the -used_in option. When specified, the -of_objects switch will only accept a single fileset or sub-design.

-used_in <arg> - (Optional) Accepts one of the enumerated values of the USED_IN property for files, and returns files matching the specified value. Valid values for this option include the following: synthesis, simulation, or implementation. Refer to the Vivado Design Suite Properties Reference Guide (UG912) for information on the USED_IN property and its supported values.

Note: This option must be used with the -compile_order option. When specified, the -of_objects switch will only accept a single fileset or sub-design.

-all - (Optional) Returns all of the files in the design, including internal files in support of IP and other objects.

-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.

Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.

-verbose - (Optional) Temporarily override any message limits and return all messages from this command.

Note: Message limits can be defined with the set_msg_config command.

<patterns> - (Optional) Match files against the specified patterns. The default pattern is the wildcard '*' which gets all files in the project or of_objects. More than one pattern can be specified to find multiple files based on different search criteria.

Examples

The following example returns the VHDL files in the design that are used in simulation:

get_files -filter {FILE_TYPE == VHDL && USED_IN =~ simulation*}

This example returns the design source files that are used in simulation:

get_files -compile_order sources -used_in simulation

This example gets a list of files associated with the specified IP core composite file (ip.xci), from the sources_1 fileset that are used in synthesis:

get_files -compile_order sources -used_in synthesis -of [get_files ip.xci]

The following example gets a list of the files found in the sources_1 and constrs_1 filesets:

get_files -of [get_filesets {sources_1 constrs_1}]

Note: If there are no files matching the pattern you will get a warning.
